I believe that the async I/O code expects you to obey the API protocol,
in particular to wait for read-ready or write-ready where it says to.
Offhand I would expect an error return in case of failure to wait
long enough, though.

Hmm, is it possible pqFlush never succeeded in writing out the whole
startup packet? It'd be useful to look at the state of the connection
object with a debugger, esp. to see if anything is still pending in the
outbound I/O buffer.
